Action Required

Three new amendments are now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators.

If you operate an XRP Ledger server, upgrade to version 1.12.0 by September 20, 2023 to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.

Amendments, New Features, and Changes

(These are changes which may impact or be useful to end users. For example, you may be able to update your code/workflow to take advantage of these changes.)

  • AMM: Introduces an automated market maker (AMM) protocol to the XRP Ledger's decentralized exchange, enabling you to trade assets without a counterparty. For more information about AMMs, see: Automated Market Maker. #4294

  • Clawback: Adds a setting, Allow Clawback, which lets an issuer recover, or claw back, tokens that they previously issued. Issuers cannot enable this setting if they have issued tokens already. For additional documentation on this feature, see: #4553.

  • fixReducedOffersV1: Reduces the occurrence of order books that are blocked by reduced offers. #4512

  • Added WebSocket and RPC port info to server_info responses. #4427

  • Removed the deprecated accepted, seqNum, hash, and totalCoins fields from the ledger method. #4244

Bug Fixes and Performance Improvements

(These are behind-the-scenes improvements, such as internal changes to the code, which are not expected to impact end users.)

  • Added a pre-commit hook that runs the clang-format linter locally before committing changes. To install this feature, see: CONTRIBUTING. #4599

  • In order to make it more straightforward to catch and handle overflows: changed the output type of the mulDiv() function from std::pair<bool, uint64_t> to std::optional. #4243

  • Updated Handler::Condition enum values to make the code less brittle. #4239

  • Renamed ServerHandlerImp to ServerHandler. #4516, #4592

  • Removed an unused TypedField move constructor. #4567

Docs and Build System

  • Updated checkout versions to resolve warnings during GitHub jobs. #4598

  • Fixed an issue with the Debian package build. #4591

  • Updated build instructions with additional steps to take after updating dependencies. #4623

  • Updated contributing doc to clarify that beta releases should also be pushed to the release branch. #4589

  • Enabled the BETA_RPC_API flag in the default unit tests config, making the API v2 (beta) available to unit tests. #4573

  • Conan dependency management.

    • Fixed package definitions for Conan. #4485
    • Updated build dependencies to the most recent versions in Conan Center. #4595
    • Updated Conan recipe for NuDB. #4615
